T @ZZ whom, it 'hi/ty concern:

Be it known that we, FRANKLIN M. REED, of Indianapolis, county ofMarion, and CORNE- LIUS R. UMBENHOWER, of Pendleton, county of Madison,State of Indiana, have invented a certain new and useful Heating-Stove;and we do hereby declare that the following is a full, clear, and exactdescription thereof, reference heilig had to the accompanying draw- Ioings, in which like figures refer to like parts. Our invention relatestoa heating-stove for burning gas or other. fuel.

What we claim as our invention will be understood from the followingdescription and claims and the accompanying drawings, illustrating oneform of stove embodying our invention.

In the drawings, Figure l is a central vertical section of said stove.Fig.'2 is a plan zo of the oil-pan or bottom of the burner. Fig. 3 is aplan of the diaphragm on which the burner is mounted. Fig. 4 is asection on the line A A of Fig. 1.

In detail we show herein a stove containz5 ing a base l, supported uponlegs 2 and with a shell 3 extending upward from the base in which theburner is locatedand which constitutes the fuel-chamber. The shell iscontin ued to form the upper part 4. These parts,

3o however, in the stove shown form one shellV with a contracted portionbetween the parts 3 and 4L. On the upper end of part Il of the shell thetop 5 is mounted on a ring of openwork 6. 7 is the bottom of the base.

8 is the door, and 9 is the outlet to the flue. l/Vithin the upperportion of the shell of the stove we suspend an internal heatingchamberl0, pointed at its lowerend and cen- 4o tral over the burner or thefire-chamber and of less diameter than the upper shell, so that thefuelchamber surrounds said internal heating-chamber l0. This internalheatingchamber is open at the upper end to the outside air through theopen-work 6. The outlet to the due is at the upper end of the outer orfuel chamber. With this arrangement, therefore, the flames and heat fromthe fuel envelop said internal heating-chamber and pass up around it andout through the Hue. There- 5o fore in addition to the outerheat-radiating surface we have the heat-radiating surface of saidinternal chamber l0, thus substantially doubling the heat-radiatingsurface. Another effect of this construction is that since the internalheating-chamber l0 is centrally located it drives the heat and Haineagainst the outershell ofthe stove, th us bringing the heat or flames indirect contact with said outer shell instead of allowing the heat 6o andflame to pass directly up through the middle of the stove and outthrough the due without imparting the heat to the wall of the stove, asis true of stoves in the usual form. In this stove the heat and flame intheir passage up through the stove are in direct contact simultaneouslywith both the inner and outer shells. To render said constructionfurther effective, means is provided for introducing air to the lowerend of theinternal chamber 7o through the conduit 13, which in the formshown leads from the bottom of the shell or stove up past thelire-chamber, whereby the `air is somewhat heated before it ent-ers theinternal chamber. Ve also provide a conduit l5, leading likewise fromthe bottom of the stove up past the fire into the upper part ofthetire-chamber, whereby the air is somewhat heated and in thatcondition is introduced through the openings 16 directly upon 8o thedame or fuel. The wall 14 separates conduits 13 and 15. Thisintroduction of superi heated air at the point indicated into thefirechamber causes it to mix with the smoke and gases, which results intheir complete combustion.

Between the base and the fire-'chamber 3 we cast an annular ring 2l,upon which we place the diaphragm 20, so that it is readily removable.Saiddiaphragmiscentrallyopen 9o and has inwardly-extending arms 22, thatare provided with upwardly-extending lugs 23. Upon the arms 22 we placethe bottom piece 24: of the burner, so'that it is held in 'place by thelugs 23. Said bottom is centrally apertured, and has around saidaperture a sleeve 25, through which the oil-pipe 26 extends upward. Saidbottom 20 has an external rim 27 and a series of openings 28 which arealso protected by upwardly extending walls 29, whereby the oil cannotescape through said bottom, but air can readily pass up through it forcombustion purposes.

On the upper end of the oil-pipe 26 We `mount an `outlet-dome 30,theopeningthere-E from being central, whereby.the=oilwi1l flaw@ so thatthe heat by the inturned top of ythef casing 32 is deflected againstthehood 31. The hood 31 is provided with aseries of apertures 33 forthevescapeof beat and intermingling` of air and gases. 34 leadscentrallyfrom the bottom `7 to carry oi any overflow of oil.

In Ithis construction of stove either foil, f

gas, or coal can be burned, as the coal-grate can `be substituted forthe oil-burner herein l shown. Also the oil-burner as here made can belifted out of the stove without disconnecting or interfering with theoil-supply pipe.

What we claim as our in ventioznand desire toasecure 'by Letters`Patent, is-

1. A stove including an outer shell centrally contracted and alsocontracted near its upper end, a smoke-outlet above the uppercontraction, an inner casing located in the .upperapartof the `stovewith the bodyof it between 'thgecontracted portions of the outer shelland parallel therewith, the upper end of said casing being open andsecured to the stove Aabove the smoke-outlet and the lower end beingtapering centrally over the fire-pot, and an air-inlet to the lower endof said inner chamber that 'leads from Vthe `bottom of the stove.

2. A stove including an outer shell with a fuel-chamber in its lowerend, an inner cas- Aing foriningan vinner air-heatingchamber oc-,copying the central portion of the upper end of the stove, anoutletopening from `the upper end of said inner-chamber, an .air-inletopening 'from the bottom of the stove `to the 'lower end of said innerchamber, and an airinlet into the fuelchamber just below said innercasing.

In Witness whereof we have hereunto affixed our signatures in thepresence `of the witnesses 'herein named.
